Why Spam Firewall ?
Spam has rapidly turned from a mere nuisance into a major security threat and financial drain for organizations worldwide. While at first spam was relatively easy to block through the use of blacklists or basic content filtering techniques, spamming methods have advanced to the point that these technologies are no longer sufficient or cost-effective. The financial costs associated with spam are large and growing. First, there is the loss of employee productivity due to time spent managing their inboxes and junk email folders, requiring employees to delete spam and block senders. But perhaps even more costly for businesses is the large volume of spam that enters company networks, which can choke mail servers and occupy expensive space in email quarantines and storage archives. This inundation of spam results in reduced bandwidth, slower email delivery, and higher storage costs. To make matters worse, spam is often a mechanism used to carry viruses, malware, and numerous other security threats which can compromise sensitive information, damage a network, and cause significant cost in terms of network downtimes and repairs to infected systems. Finally, there is the challenge of successfully blocking spam while at the same time avoiding the accidental deletion of valuable business email. Therefore, Cheap and Free-of-Cost Anti-Spam Services are becoming expensive for the organizations. Clearly with such an influx of unwanted, dangerous junk mail, it is necessary for organizations to broaden their efforts at combating spam by applying a new generation of anti-spam solutions that leverage multiple layers of protection, including maintenance services.
